The quarries closed in the 1940s, and were filled with ash from
Halifax Gas Works and from Paton & Baldwin Limited.
A driver for Paton & Baldwin Limited was killed when he
reversed his lorry too near the edge of the quarry and went over the

In 2003, there were proposals to convert the mill into residential
property with 134 apartments – to be known as Millroyd Island
on account of its location between the Calder and the Calder &
Hebble Navigation.

When sales opened in autumn 2003, it was claimed that 100 flats were
sold in 4 hours – before work had even started.
The conversion was completed in 2004.

In autumn 2004, the developer was proposing that further blocks of
flats be built there

A footpath runs from the top of Straight Lane, diagonally across the
fields, through the wall at the bottom, and up into Mixenden.
On going through the wall, the Mill was over on the right, as you
head towards Mill Lane.
Some time back, mobile part of the stream connection was still
visible under the vegetation.
The quickest way, however, is along the track just up Mill Lane a
little from the bridge.

It was on the Mixenden part of Fold Farm, part of the
cottage industry system.

In 1914, Hare Mill, Todmorden ran into financial and other
difficulties and was wound up.
It was bought by the newly-formed Mons Mill Company Limited and the
name was changed to Mons Mill after the World War I Battle
of Mons.
The Mons Mill (1919) Limited company took over the mill in
1919.

The mill was originally powered by
an engine built by Carels of Belgium which drove about 73 belts.

In the 1950s, it was bought by the Lancashire Cotton
Corporation.
The mill was closed for a time from
18th March 1953,
when there was an epidemic of smallpox.

In 1964, the company was taken over by Courtaulds.
In 1968, the mill closed.
From 1971, the building was used by Ward & Goldstone Limited
until the 1990s when they left.

In 197?, the mill chimney was reduced by 30 ft.
In 1986, the mill chimney and the engine house were demolished.

The site was cleared in March 2000.

The domed building which housed the offices and board room is now a
